To find the GCF of two numbers, you first need to break them down into their prime factors. For 140 and 252, these are: 140 = 2x2x5x7 252 = 2x2x3x3x7 The next step is to identify common prime factors. In this case, both numbers have two 2s and a 7 in their prime factors. To find the GCF, we simply multiply these common prime factors together: 2x2x7 = 28. Thus the greatest common factor of 140 and 252 is 28.
